CVE-2024-37185
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code in pre-installed applications on OpenHarmony devices through an out-of-bounds write. It affects OpenHarmony v4.0.0 and earlier versions. Attackers can potentially gain control over affected systems without user interaction.
💻 Affected Systems
- OpenHarmony
📦 What is this software?
Openharmony by Openatom
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing remote code execution with highest privileges, enabling data theft, persistence, and lateral movement.
Likely Case
Remote code execution in pre-installed app context, potentially leading to data exfiltration, surveillance, or further exploitation.
If Mitigated
Limited impact with proper network segmentation and minimal exposed services, though local network attacks remain possible.
🎯 Exploit Status
Remote exploitation without authentication is indicated by the description, though specific exploit details are not publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenHarmony v4.0.1 or later
Vendor Advisory: https://gitee.com/openharmony/security/blob/master/zh/security-disclosure/2024/2024-07.md
Restart Required: Yes
Instructions:
1. Check current OpenHarmony version. 2. Update to v4.0.1 or later via official channels. 3. Reboot device after update. 4. Verify update completion.
🔧 Temporary Workarounds
Network Segmentation
allIsolate OpenHarmony devices from untrusted networks and internet exposure.
Application Restrictions
allDisable or restrict network access for non-essential pre-installed applications.
🧯 If You Can't Patch
- Segment affected devices on isolated network segments with strict firewall rules.
- Implement application allowlisting to prevent execution of unauthorized code.
🔍 How to Verify
Check if Vulnerable:
Check OpenHarmony version via system settings or command 'getprop ro.build.version.ohos' - if version is 4.0.0 or earlier, device is vulnerable.Check Version:
getprop ro.build.version.ohosVerify Fix Applied:
Verify version is 4.0.1 or later using same command and ensure no abnormal application behavior.📡 Detection & Monitoring
